Abstract
A method of detecting a frame boundary of a received signal in a digital communication system, the method including: generating a delayed signal by delaying the received signal by a predetermined period; calculating a correlation value by correlating the received signal with the delayed signal for a predetermined correlation length in a time domain; and determining a timing index corresponding to a maximum value, as a frame boundary index, from a plurality of correlation values which are obtained by repeating the calculation. According to an embodiment of the present invention, a correlation calculation in a time domain is performed without oversampling, in a limited length including a cyclic prefix. Accordingly, accuracy of frame boundary detection may be improved and complexity of hardware and software may also be reduced.
